Yes to VPN because this could happen https://torrentfreak.com/piracy-app-cotomovies-shuts-down-apologizes-and-exposes-users-190911/

I wouldn't recommend it. VPNs tend to cause more trouble than what they're worth in iptv.

your always better to have one just in case, they try to put a block on the ppv's and the premier league football

Alternative is to avoid the big 6 isp's. Go with a quality ISP like Idnet or AAISP. Both refuse to censor anything, both are committed to not throttling anything. With idnet or AAISP you'll never need to use a vpn with iptv (and they are likely to be faster as well).

yes, absolutely necessary, don't let the reseller tell you otherwise.

the problem now is copyright trolls that take the fact that you are
using your real ip, evidence of copyright materials you watched,
then they fill out a legal request to your ISP and start harassing
you with collection notices in the thousands of dollars.
it would not surprise me in the least if some of the resellers here
actually siphon off their real IP data and feed it to such trolls, as
it's another potential profit center for them if you don't buy their
recommended paid vpn services they get referral fees from.

this is also why you should NEVER pay a reseller with real info,
always use a VISA Gift Card or Bitcoin, never paypal of real CC.
the reason is because you are making your real IP date far more
valuable to copyright trolls, since now they have your real info
and don't need to bother your local ISP for it, thus the reseller
of iptv profits far more off your data referral to that troll farm.

this of it another way... if you were shoplifting, would you stop
and smile at the security camera, or would you keep your head
down while wearing a hoodie, baseball cap and dark sunglasses...

Do you need a VPN if you only use a service to watch iptv and don't download anything?
